BM-Depth filter cartridge made of ultrafine PP-Bi-component-fibers


The BM-Depth filter cartridge consists of 100% ultrafine Polypropylene-Bi-component-fibers which are thermally bonded together at their cross points. The attained ultra pure and exceptionally compact filter matrix assures a repetitious and absolute accuracy of filtration characteristics for top quality applications. The BM-filter cartridge is a typical depth filter with an absolute and graded density pore structure and finer filter ration from the outside to the inside. The stable depth filter structure assures secure particle retention over the whole life time even at high ranges of differential pressure.
